' Application filed May 20, 1909. Serial No. 419?,241.

Be it known that. I, WHITON BAILEY, a citizen of the United States,residing at Spokane, in the county of Spokane and State of 'Washington,have invented a new and useful Time-Controlled Mechanism, of which thefollowing is a specification.

This invention has reference to improvementsin timecontrolled mechanismand itsv designed to'cause the release of stored-up power'after apredetermined time interval so that such stored-up power shall in turncause the operation of another mechanism to accomplish any desiredresult' In accordance with the present inventionpower is stored for theactuation-of the time controlling mechanism and such power issufiiciently in excess of the power needed for'thetime mechanism so thatat the ex piration {of the redeter mined time there I shall still .besucient'power to cause'the actuation of thefmechanism designed to beoperated'after the time interval has. elapsed;

The invention is designed morepa-rticularly for the actuation of anelectric switch to complete or rupture an electric circuit as the casema be or to cause the-starting I I or stopping .0 any desiredmechanism01!? a clock trainlwhich may any character whatsoever wherein the pres-.ent invention may be applicable.

The invention will hey-best understood from a consideration of thefollowin detail description taken in connection wit the accompanyingdrawings forming a part of thisspecificatiomin which drawings,

Figure 1 is a partially diagrammatic'ele- 1 vation of an apparatusconstructed in ac-.

cordance with the present. inventioinw'it-h parts broken away todisclose more remote parts. Fig. 2 is a side elevation of the struc--ture shown in Fig. 1 with parts in section.

'ter has fast theretoat one end a ratchet 4 adjacent' to the wheel 3 andthe latter carries a spring-actuated pawl .5 so that when the arbor 3 isturned in one direction the ratchet 4 will engage the pawl 5 and cause arotative movement ofthe wheel 2, and

when the arbor 3 is rotated in the opposite direction the ratchet i willride'idly under quiescent.

The arbor 3 has fast. thereto a pinion 6 'which in turn is normally inmesh with a gear wheel 7 having a space 8 onits periphery free-from gearteeth sov that the gear wheel 7 is in e ect a mutilated gear; The

' the. pawl 5 and the wheel 2 willreinain' 7 gear wheel 7 is. mounted onan arbor 9 car- 1 ried by a yoke 10 which latter is ivo'ted at I thefree end of its legs to a suita le casing 11 carrying the clock train 1.The yoke 10 is under. the normal control of a spring 12 telndipmat alltimes to maintain the'gear ,w as

in mesh withzthe' pinion 6, and a stop pin 13 limits the movement of theyoke .1O,under. the action or the spring .12.

East to the arbor 9 is one end of a spiral spring 14 while the otherend'of this spring is made fast toa pin 15 on the yoke 10. The-- arbor 9extends through a slot 16in a dial 17 and exterior to the dial the arborcarries an arm 18 parallel with said. dial and extendi'n thereo The dialcarries a stop pin 19 in the path of the arm 18 to limit the movementofthe arm 18 in one direction which direction is that, in which the arm 18travels .on the unwinding of the spring 14;

Iii-the path of the arm 18, or of a manip ulating handle 20 on the endof the arm, are.

other arms 21 radiating from a spindle 22 projecting from a switch 23,which latter'is only indicated in the drawings and may be considered asof the ordinary snap switch,

type for the control of electric circuits.

The ordinary snap market has four positions in a complete rotation,.thatis the circuit is completed twiceand broken twice in the completerotation of the switchand with such a switch there are tolpapproximatelythe periphery I switch found on the provided fourarms 21. If. the switchbe of v another type then a lesser number of arms may answer. In thepath of the arms is an elastic stop 24 so disposed that when the switcharbor 20 is turned to a position where the switch is about to move fromthe active to the inactive position or from the inactive i to the activeposition, the stop 24 will hold the switch against the tendency-toreturn to the position. from which it was moved, it

being common in. switches ofthis type to.

turn the arbor 22 sufficiently to put a. contained spring under tenslonbefore the switchmember .proper is released to move with'grea'tirapidityfrom one position to I another. The purpose of thestop 24 is to hold theswitch insuch position that a-comparatively short movement'of the arm 18will: cause the movement ofthe switch "from its active to its inactiveposition or from its inactive to its active position. I Let it beassumed thatit be deslrable to 'turn electric lights on and after apredetermined time to cause the'breaking of the .circuit and theezitingui'shing of the lamps. The movable part of the switch 23 isturned so that'an arm.21 is engaged by the stop 24 vwith the switchmechanism inya position where a slightly farther movement of the. arm 21will cause the switch to snap to the open position. In the meantime thearm 18 is moved'clockwise as viewed in Fig. l tothe causing the arbor-3to move in a irection' desired extent winding up'the sprin 14 .and

inactive to the pawl 5. When the arm 18 is released the reactive effectof the'spring 14 will cause the arbor to return in the re-' versedirection but now the ratchet 4 will engageth'e pawl 5, andmotion willbe transmitted through the clock train. The return'movement of the arm18 under the 'ac- '-tion ofthe spring 14 will be only so rapid.

as will be permitted by the'action of the escapement ofrthe clock trainso that the desiredtime will elapse before the arm 18 will again engagethe switch actively. 'Ihe rela- I tion of the smooth portion 8 of thegear 7 to blow thereto.-- x

the toothed portion thereof is such that the toothed ortion will moveout of engage ment wit the pinion 6 when the arm 18 has approached an.arm 21 of the" switch .23 so that after the expirationof"the'predeter'- mined time the arm 18 is released to the full force ofthe spring 14 and moves with rapidity a ainst' the arm 21 of'the switch23 and the. atter'is actuated to the open po-.

sition at once, the arm l8-beingbultnnately arrested by. en gement witht, aj fiibp 19. The relation 0 the smooth of the gear wheel 7 may besuch'thatt e 'arm L8 will begin its rapid. movement under the action ofthe spring 14 before it reaches'the switch arm 21 and therefore willdeliver a hammer The' arm 18 may betprovided with a manipulating handlevadapted to engage the arms 21 or the handle may be otherwise 10- 1 catedthan shown and other means carried by the arm may be utilized forcausing. the

actuation of the switch; Should it transpire that the switch 23 should le-actuated at an earlier time than that for which the mechanism is setthen an attendant may move the yoke 10 against the action of the spring14 so asto carry the gear wheel 7 out of engagement w1th the pinion 6and then the arm 12 will become immediately active under the stress ofthe spring 14 and cause the actuation of g the switch 23 .as thoughreleased at the expiration of the time limit.

The power stored up in setting theappa ratus is sufficient not only toactuate the time cohtrolling side of the apparatus but also to actuatethe devices to be set in motion after the expiration of thepredetermined time.

What is claimed is 1. In time controllin bor, a driving spring orthexarbor, adial traversed by the arbor, a mutilated gear on the arbor, amanipulating arm on the arbor for putting the spring under tension andin turn driven by the spring, a clock train in operative relation to themutilated gear, a

stop on the dial in the path of the manipulating arm, and powercontrolling means in mechanism, an arthe pathof the arm betweenthe pointwhere the spring is released by the mutilated gear from. the clockmovement and the stop.

2. In a time controlling mechanism, an arher, a spring secure'd theretofor" imparting rotative movement to the arbor, a manipu-.

lating arm on the arbor for winding the spring, a dial traversedby thearbor and in operative relation to the mani ulating arm, a stop on thedial in the path 0 the manipulating arm, retarding means for the sprmand arbor, means for causing the release -0 the. spring and arbor fromthe retarding means before the manipulating arm reaches the-stop, andpowercontrolling means in the-path of thearm between the point where itis released from the retarding means and vthe stop.

3. In time controlling mechanism, a clock train, a mutilated gear in oerativerelation to the clock train, a pivote frame carrying the gear, aspring tending to move the "frame in a-direction to maintain the gear inoperative relation to the clock. train, an arbor mounted in the frameand constitutin a -support for the gear, a sprin connecte to the arborand frame and ten ing whenput. I

under tension to rotate the arbor, an arm on the arbor for winding thespring and in turn moved by the, arbor underthe action of the spring,and power-controlling means in the ath of and actuated by the armwhenreeased to the unrestricted action of the spring. a

In testimony that I claim the foregoing as my ,own, I havehereto-afiixed my slgnature in the presence of two witnesses.- v
